The logic for Dextrose PWO is the following:
Muscle glycogen stores are replenished at a maximum rate by consuming maximally high GI carbs, and thus protein synthesis occurs at an optimal rate; additionally, an insulin spike will serve to inhibit cortisol and hence muscle catabolism while also promoting maximum nutrient uptake.
The logic against Dextrose PWO is the following:
Resistance training (i.e. weight training) is a low volume, high intensity activity and consequently does not significantly deplete muscle glycogen. Hence, the protein consumed PWO is of primary importance, and low GI carbs can be use to replace what little glycogen has been expended while minimizing the insulin spike and thus the fat additive affect of high GI carbs such as Dextrose.
Personally, I go with oats and whey nowadays. I occasionally thrown in around 10g of dextrose on the offchance that i've done some cardio to cause a glycogen depletive effect. |
